How to create a claims and defenses evidence matrix for Employment Discrimination Matters

Create the matrix by separating each discrimination theory into propositions counsel must prove or contest, then linking each proposition to supporting evidence, adverse evidence, foundation issues, and unresolved gaps. Start with the governing statute, forum, and procedural posture—not a generic discrimination checklist. Trace who made the employment decision, what they knew, and which reasons they gave. The deliverable is a source-linked working table that distinguishes evidence from inference, shows the current assessment, and assigns targeted follow-up without presenting disputed facts as established conclusions.

When to use this workflow

Use this workflow after initial collection, before focused discovery, or when assessing a motion or settlement position. It serves employee-side counsel, employer-side counsel, and in-house teams working with litigation counsel. A concrete trigger is a record containing competing explanations for termination, discipline, promotion, compensation, or another challenged employment decision.

Limit each matrix to a defined decision or related decision group. Separate statutory theories and employee-specific facts even when they share documents. A termination allegation should not silently absorb a promotion allegation because the same manager participated in both.

This guide uses a US federal district-court orientation. Confirm the statute, controlling authority, local rules, orders, and procedural stage. Federal civil and evidence rules have defined scopes; do not automatically apply them to state proceedings, arbitration, or agency investigations. See Civil Rule 1 and Evidence Rules 101 and 1101. (uscourts.gov)

The steps below are workflow recommendations, not a universal substantive discrimination test.

What you need

Gather the operative complaint or charge, answer or response, relevant orders, and counsel’s current identification of claims, defenses, and remedies. Maintain an authority worksheet specifying each applicable element, burden, causation question, and procedural posture.

For the challenged employment decision, assemble:

• Job descriptions, personnel records, reviews, disciplinary histories, and applicable policy versions.
• Recommendations, approval chains, scoring materials, decision communications, and relevant messages with attachments.
• Agency submissions, discovery responses, interview accounts, and available deposition testimony.
• Potential comparator records, candidate-selection criteria, and collection limitations.
• Payroll, benefits, and job-search records relevant to disputed remedy propositions.

Assign stable document IDs and preserve page, paragraph, Bates, or transcript references. Identify missing attachments and incomplete records. Record collection boundaries so an unsuccessful search is not treated as proof that an event never occurred.

Designate who may edit the matrix and who verifies legal standards. Keep counsel’s analysis distinct from source records and apply appropriate access controls to sensitive personnel information.

Use the template

The companion template is Employment Discrimination Matters — Claims and defenses matrix. Copy this table into your working document or spreadsheet. Use one row per proposition, not one row per document.

In Theory / proposition, identify an element, asserted defense, factual explanation, or remedy issue. An employer’s explanation is not automatically an affirmative defense.

Use Burden / authority for the applicable stage-specific burden and pinpoint authority. Both proof columns need source IDs, precise locations, and relevance—not merely document titles. “Supporting” means supporting the stated proposition, regardless of counsel’s represented party.

Use Foundation / limits for authenticity, hearsay, uncertain timing, incomplete context, and witness-knowledge limits. In Assessment / action, separate the present conclusion from the next task: “unresolved; obtain approval record.” Distinguish “not collected,” “not located,” and “disputed.” Record priority and completion criteria alongside the action; identify its owner and review status in the final column.

Reference stable row IDs rather than spreadsheet coordinates that change when sorted.

Step by step

1. Define the decision and legal propositions

Write a scope statement identifying the employee, challenged action, actors, relevant period, and statutory theories. Distinguish the decision date, communication date, and effective date; do not assume they coincide.

Translate the verified legal framework into discrete propositions. Separate liability, defenses, and remedies. For example, an alleged discriminatory selection reason and a disputed compensation-loss period require different evidence and analysis. Distinguish a burden of production from the ultimate burden of persuasion wherever the researched framework does so.

Do not substitute a generic checklist for unresolved law. Record the specific research question and responsible lawyer.

Record: Proposition labels, stage-specific burdens, pinpoint authority, and assigned legal questions.

2. Establish source and event references

Create a source register connecting each document ID to its location, custodian, date, and completeness. Link decision events to sources without expanding the matrix into a full chronology. For testimony, identify the witness, account date, and transcript or interview-note location.

Separate firsthand observation, reported statements, inference, and counsel commentary. An interview summary attributing a statement to a manager is not the manager’s sworn testimony. Preserve inconsistent versions and identify which documents the witness actually reviewed.

Record: Exact source references and qualifications such as “interview account; not sworn,” “attachment missing,” or “creation date unverified.”

3. Map supporting and adverse proof together

Read the strongest supporting and contrary material for each proposition. Explain the connection: “approver received revised scores before selection” is more useful than “helpful email.” One document may support one row and undermine another.

Identify intermediate facts needed for an inference. A complaint stored in an HR system does not, by itself, establish that a decisionmaker read it. A favorable review may bear on a performance explanation without resolving what happened afterward.

Avoid numerical confidence scores unless the team has a defined, defensible method. A short assessment with stated reasons is usually more informative.

Record: Both proof columns, proposed inferences, contrary explanations, and missing links. An empty adverse-proof cell should identify either the completed review scope or an assigned search.

4. Trace decision reasons over time

Compare recommendations, approvals, employee communications, agency submissions, discovery responses, and testimony. Attribute explanations to speakers and dates. Test whether differences are contradictions, additional detail, or differences in participants’ knowledge.

In Reeves, a prima facie case combined with sufficient evidence that the employer’s justification was false could permit a finding of intentional discrimination, but did not compel it. The case involved an ADEA verdict reviewed under Rule 50; it does not establish every statute’s framework. See Reeves, 530 U.S. 133, 147–149. (govinfo.gov)

Record: Material reason disputes, source sequences, alternative explanations, and the legal significance requiring claim-specific authority. Do not label every elaboration “pretext.”

5. Test comparator assertions against actual records

Compare role, supervisor, decisionmaker, location, period, conduct, qualifications, disciplinary history, and outcome as relevant to the researched theory. Mark unknown values explicitly. Preserve candidate-selection criteria and reasons for excluding others.

Similar titles should prompt factual comparison, not end it. Determine whether employees were evaluated through the same selection process and whether identified differences affected that decision. Keep those factual findings separate from counsel’s legal comparability assessment.

If collection covered only the claimant’s team, do not describe it as organization-wide. Avoid treating uncollected disciplinary history as a clean record.

Record: Material similarities and differences, source references, population limits, and bounded requests for missing records.

6. Separate evidentiary usability from factual relevance

Assess how each significant item could be established through a witness, record source, or other foundation. Evidence Rule 901 requires sufficient evidence that an item is what its proponent claims. Rule 803(6) separately addresses the regularly conducted activity hearsay exception; authentication does not resolve embedded statements or other objections. See Rules 901 and 803(6). (uscourts.gov)

Avoid “HR record—admissible.” Identify the entry, author, information source, potential foundation witness, and unresolved objection. Flag privilege and confidentiality for separate review without treating those concepts as interchangeable.

Record: Item-specific foundation questions and potential witnesses, separate from factual significance. Preserve the distinction between a useful investigative lead and evidence counsel expects to present.

7. Convert gaps into prioritized assignments

Choose tasks that could materially change the assessment: obtain a scoring attachment, interview the approver, reconcile a policy version, or research a disputed burden. State which proposition the result will affect and what constitutes completion.

Federal discovery under Rule 26(b)(1) concerns nonprivileged material relevant to a claim or defense and proportional to the case; discoverability does not require admissibility. Shape requests accordingly rather than using the matrix to justify unrestricted personnel-file collection. See Rule 26(b)(1). (uscourts.gov)

Record: Current assessment, bounded action, priority, owner, and completion criterion. Date substantive updates and preserve the earlier assessment’s basis so counsel can explain what changed.

Worked example

Fictional scenario: Mara Ellison, age 58, alleges age discrimination after fictional employer Cedar Quay Instruments terminated her during a departmental reduction. Cedar Quay says selection scores drove the decision. Counsel has a recommendation email, incomplete scoring workbook, termination letter, agency submission, and selected personnel records. All parties, records, and facts below are fictional.

The recommendation predates the termination letter; final approval is missing. The agency submission discusses scoring and performance. Counsel cannot determine whether performance fed the original score. Retained employee Nolan Vale, age 39, held the same title and reported to the same manager, but his complete selection and disciplinary records are unavailable.

The three entries illustrate contested factual propositions, not a complete ADEA elements or defenses checklist. Their legal-framework cells remain expressly unresolved rather than implying that Reeves supplies the missing authority.

The matrix changes the immediate decision. Counsel should not characterize the agency submission as a proven reversal: the missing attachment may connect performance to scoring. The roster does not establish legal comparability. The manager’s note may describe a genuine later development or expose a timing problem. Targeted verification comes before a firm pretext assessment.

Common mistakes

• Combining distinct theories. Split rows when the action, statutory theory, burden, or remedy differs; reuse source references where appropriate.
• Recording only favorable evidence. Require adverse-proof review and explain whether contrary material changes the assessment.
• Calling every changed explanation pretext. Attribute reasons, compare timing, and distinguish contradiction from added detail.
• Treating missing records as negative proof. Identify collection limits and distinguish an unsuccessful search from evidence that no record existed.
• Treating the matrix as exhibit-ready. Rule 1006 evidentiary summaries and Rule 107 illustrative aids have different requirements. A working spreadsheet is not automatically admissible. See Rules 1006 and 107. (uscourts.gov)

Final quality check

• Each row states a discrete proposition and category.
• Legal standards and burdens have verified, applicable authority or an assigned research issue.
• Source IDs and pinpoints resolve to the correct records.
• Supporting and adverse proof have both been reviewed.
• Decision dates, speakers, and inferred knowledge are distinguished.
• Comparator limits and foundation questions remain visible.
• Material open issues have owners, bounded actions, and stated consequences.
• The dated version identifies its reviewer and current assessment without implying final legal approval.

Frequently asked questions

Should the matrix be organized by document or claim?

Organize by proposition within each claim or defense. Maintain a separate source register. This exposes missing proof that a document-by-document digest may conceal.

How should witness disagreements appear?

Record both accounts with dates and pinpoints. Separate firsthand knowledge from inference, identify documents reviewed, and assign the factual question needed to reconcile the disagreement.

Can one matrix cover several employees?

Yes, if employee, decision, theory, and sources remain unambiguous. Use separate row groups where actors or selection processes differ; do not erase individual factual distinctions through aggregation.

When is the matrix ready for counsel’s decision?

When material propositions have verified sources or explicit gaps, contrary evidence is visible, and unresolved issues have consequences and owners. Readiness means counsel can evaluate uncertainty—not that every issue is resolved.
